Kuti uone kuti pombi inosangana nezvinodiwa zvemakemikari eGiredhi B zveese matatu zviyero, API 5L, ASTM A106, uye ASTM A53, iyo kemikari yemhando yezvinhu inofanirwa kudzorwa zvakasimba panguva yekugadzira.Izvi zvinotevera zvinodikanwa zvemakemikari ekuumbwa kweaya matatu zviyero:
API 5L Giredhi B Chemical Kuumbwa
ASTM A106 Giredhi B Chemical Kuumbwa
ASTM A53 Giredhi B Chemical Kuumbwa
